Vital Signs: How Often and What to Do




Case Example: A nurse sees a 55 year old male inmate at sick call. His sick call request says that he has a sore throat and heartburn. During the nurses’ assessment he has body aches, chills and constipation in addition to the sore throat and heartburn. The patient’s vital signs are T=100, P = 92, R=16, BP=170/100. The patient is seen periodically for treatment of hypertension and his next scheduled appointment is a month and a half from now. The nurse gives the patient milk of magnesia and ranitidine per the nursing protocol for heartburn. The nurse also schedules the patient for ….

What do you think the other parts of the nurse’s plan of care for this patient include? This is the fourth and last of a series of posts about vital signs in correctional nursing practice. Other case examples used in this series have involved urgent or emergent situations. This time the case example takes place during sick call, a non-emergent ambulatory care encounter when a significantly elevated blood pressure is found during the nursing assessment. It raises the question of when and how often correctional nurses should take vital signs?

How often should vital signs be taken? It was interesting to find out while researching for this post that there is no body of evidenced based research to suggest when and how often vital signs should be taken (Storm-Versloot et al. 2014). However the information provided by a complete set of vital signs has been considered valuable in provision of patient care for the last century. Likewise we haven’t needed evidenced based research to know that having a parachute significantly affects survival in the event of a plane crash.

One of the reasons for failure to identify and treat deterioration in patients’ conditions was that vital signs have not been monitored regularly but instead left to nursing discretion. A best practice recommendation is to establish guidelines for when vital signs are to be taken. Expert recommendations applied to correctional health care are to take vital signs as follows:

  • Ambulatory care: At the time health care attention is sought for non-emergent health care concerns. If abnormal, daily thereafter until stable or referred to another level of care.
  • Chronic care: According to nationally established clinical guidelines for the initial work up of the patient’s condition and then according to a plan of care established by the provider individualized to the patient’s needs and goals (National Commission on Correctional Health Care 2014).
  • Emergency care: At the time health care attention is sought for an urgent or emergent health care concern. If abnormal, every 15 minutes until stable or referred to another level of care. If normal, every hour while receiving emergent care (Armstrong, Clancy & Simpson 2008).
  • Inpatient care: On admission to an infirmary or medical observation bed at the correctional facility. If abnormal, every 30 minutes until evaluated by a physician. If initial vital signs are normal, subsequent vital signs should be taken every four hours for the first 24 hours after admission. After the first 24 hours if vital signs are stable and within normal limits, every six hours thereafter (Bunkenborg et. al 2012, Australian Commission on Quality & Safety in Healthcare 2009).

One of our readers asked whether vital signs should be taken as part of the routine screening for placement in segregation. My inclination is that if there was violence or use of force immediately prior to placement in segregation, taking vital signs should be taken as an emergent intervention and be repeated an hour after placement as well. If abnormal then the patient should be referred to a higher level of care and vital signs monitored more closely until stabilized. What do you think?

Taking action when vital signs are abnormal. Another reason for failure to identify and treat deterioration in patients’ conditions was that assistance was not requested or not provided timely (Moldenhauer, Sable & Chu 2009). This has led to the recommendation that health care programs develop “track and trigger” systems. These are procedures which establish expectations for the frequency of vital sign monitoring, set parameters for abnormal findings and specify the actions and timeframes by which subsequent action is to be taken (Berwick, Hackbarth & McCannon 2006). For example criteria such as these trigger a referral for a higher level of medical attention within fifteen minutes at the Denver Health Medical Center:

  • Temperature: greater than 102.2°.
  • Pulse: less than 50 or more than 120 beats per minute.
  • Respiration: less than eight or more than 28 per minute.
  • Blood pressure: systolic blood pressure less than 90 mmHg or a sustained diastolic blood pressure greater than 110 mmHg.
  • Neurologic: confusion, agitation, delirium, lethargy, difficult to arouse, difficulty speaking or swallowing, any acute change in pupillary response (Moldenauer 2009).

While correctional facilities are not hospitals, they are healthcare organizations and inmates are unable to seek healthcare anywhere but within the program offered at the facility. The health care programs in the Oregon and Georgia Department of Corrections have developed similar protocol for the recognition of and actions taken with regard to patients whose physiologic condition is deteriorating (LaMarre 2006, Puerini 2015).

In closing, the standard for the practice of nurses with regard to patient vital signs is to:

  1. Take and record vital signs frequently
  2. Recognize patient’s physiological deterioration and the urgency of the situation
  3. Summon appropriate assistance
  4. Communicate findings and recommended actions clearly, sensibly and with confidence
  5. Give a deadline for response to the patient care situation (Kyriacos, et. al. 2011).

Vital Signs: Interpretation and Synthesis


Doctor at workA case example: It is Saturday evening at a large prison that houses medium and maximum security men. The facility medical department is staffed twenty four hours a day seven days a week with both registered and licensed practical nurses. It has a twelve bed infirmary and two providers are on site Monday through Friday and rotate call each week. At 7:30 pm a nurse is called to assess an inmate who has been assaulted in the gym. He has a bruise next to his left eye, a small laceration on his left forehead and another on his scalp (left). He reports no loss of consciousness. The injuries are treated and he is cleared to return to housing. At 10:30 pm nursing is called again because the inmate is lying in his segregation cell and is not responsive to verbal inquiry by the correctional officers. The inmate is shaking and his verbal response to the nurse during the assessment is slow; he complains of a headache. His vital signs are T= 95.6, P = 106, and BP = 166/94.

This case is a good example of the kind of situation correctional nurses face and the clinical judgments they are required to make. Nurses are the first health care professional an inmate is likely to see when they have a medical problem and it is the nurse who will determine the inmate’s subsequent access to care. In this case the nurse’s initial assessment and resulting decisions had a deadly impact on the inmate. It is not just the vital signs themselves but the interpretation and synthesis of this data in the context of the particular circumstances of the patient that define the practice of nursing. Clearly the inmate’s vital signs are abnormal at 10:30 pm after being found lying, unresponsive, on the floor of his cell. Can you explain what is going on physiologically with this inmate? What do you think his vital signs would have been at the time of the nurse’s initial assessment and what do you think they would have been an hour later? Can you explain why?

Body temperature is the difference between the amount of heat produced as a byproduct of metabolism and the amount of heat lost. The hypothalamus is the control point that maintains our body temperature between 96.8°F and 100.4°F. The body reduces core temperature by sweating, vasodilation and inhibiting heat production. Vasoconstriction and shivering increase or preserve core temperature. Heat loss is controlled by radiation, conduction, convection, and evaporation. The skin provides insulation, senses temperature and is the site of vasoconstriction or dilation. Factors affecting body temperature include age but also exercise, hormones, time of day, stress and the environment.

Abnormal temperatures are those over 100°F or repeated temperatures under 99°F or a 1°F increase over the patient’s baseline temperature. Temperatures in children are more labile until puberty. The elderly may run lower body temperatures and they have less ability to regulate their body temperature in extremes of cold and warmth.

Higher than normal temperatures can be the result of excessive heat production as in infection and/or the inability to promote heat loss. For example in hot weather the elderly, and those with cardiovascular disease, diabetes, alcoholism, hypothyroid conditions as well as those who take certain medications are less able to rely on the hypothalamus to produce heat loss and so are at greater risk of heat stroke when environmental temperatures are high. Diaphoresis which promotes heat loss by evaporation can result in dehydration and electrolyte imbalance from a deficit in fluid volume. Lower than normal temperatures result from the inability to control heat loss and/or the body’s ability to produce heat is overwhelmed (Fetzer 2013, Rathbun & Ruth-Sahd 2009). The patient’s low temperature in the case example is most likely related to his head injury and an inability to control heat loss.

Respiration is the body’s mechanism to exchange oxygen and carbon dioxide between the atmosphere, blood and cells and involves three processes:

  1. Ventilation, which is the movement of air in and out of the lungs. When we assess the rate, depth, rhythm and symmetry of respiration we are evaluating the patient’s ventilation.
  2. Diffusion is the exchange of oxygen and carbon dioxide between the lungs and the red blood cells. Oxygen saturation and blood gasses are means of assessing diffusion
  3. Perfusion is the distribution of red blood cells carrying oxygen and carbon dioxide throughout the body and back to the lungs. Capillary refill and oxygen saturation are methods used to assess perfusion.

Respiratory control lies in the brain and responds to levels carbon dioxide, oxygen and the pH level in the arterial blood by changing the rate of ventilation. Ventilation also requires muscular effort to move the diaphragm, abdominal organs and rib cage so that air moves into and out of the lungs.

A normal respiratory rate for adults is between 12 and 20 breaths per minute and for adolescents between 16 and 20 breaths per minute. Oxygen saturation rates are normally between 95 and 100%. A change in the character of respirations is as important as the rate (Fetzer 2013). Abnormal respirations should be further evaluated by listening to chest sounds. Critical thinking about abnormal respiration will consider conditions which:

  1. reduce the capacity of the body to carry oxygen (e.g. anemia, carbon monoxide poisoning, shock or dehydration).
  2. reduce the concentration of oxygen (e.g. airway obstruction, overdose, or altitude).
  3. cause an increased metabolic rate (e.g. pregnancy, exercise or wound healing).
  4. affect movement of the chest wall (e.g. pregnancy, obesity, trauma, neuromuscular disease and injury to the central nervous system. Archer, 2013).

Respiration is easiest vital sign to take but least likely to be assessed and yet is the most sensitive and earliest indicator of an impending adverse event (Chua et al. 2013, Elliott & Coventry 2012). Consistent with this finding, the nurses in the case example did not assess the inmate’s respirations. Given the description of the incident what effect do you think there would be on the inmate’s respirations and why?

Pulse is the rhythmic flow of blood pushed into the peripheral artery caused by the contraction and relaxation of the heart. It provides information about cardiac output including:

  1. the conduction of electrical stimuli in the heart (rhythm),
  2. the volume of blood ejected from the heart (strength) and
  3. distributed through the peripheral arteries (equality).

A normal pulse rate for adults is 60 to 100 beats per minute and for adolescents is 60 to 90 beats per minute (Fetzer 2013). Mechanical, neural and chemical factors regulate the heart’s contraction and flow of blood. Cardiac output is affected by hemorrhage and dehydration but also by coronary artery disease, pulmonary disease and diseases of the heart valves (Archer 2013). Heart rate will adjust to maintain cardiac output but only to an upper limit of 140-150 beats per minute (Dickenson E.T. & Lozada K.N. 2010). Conduction (heart rate) is affected by ischemia, abnormal heart valves, anxiety, drugs, caffeine, alcohol, tobacco, electrolyte and acid-base imbalances. Heart rate will be higher during exercise, pregnancy, and with fever (Archer 2013). The heart rate in the elderly is slower to change in response to cardiac output (Fetzer 2013).

In the case example the inmate’s pulse was 106 beats per minute, which is high. It is hard to judge the significance of the finding because we don’t know to what extent this is a change from his baseline vital signs or when he was first evaluated earlier in the evening. This rate could reflect hemorrhage but it could also be an outcome of head injury.

Blood pressure reflects the hemodynamic variables that maintain blood flow and oxygenation in the body. The systolic blood pressure reading is the point at which the ventricles contract and blood is ejected into the aorta at the highest pressure. The diastolic reading is the moment that the ventricles relax and the artery wall is at the lowest pressure. Cardiac output, peripheral resistance, blood volume, blood viscosity and elasticity of vessel walls all affect each other and ultimately affect blood pressure (Fetzer 2013).

Normal blood pressure for adults is considered 120/80 mm Hg and for adolescents 14 to 17 years of age normal is 119/75 mm Hg. Knowing the patient’s usual blood pressure is helpful in identifying if the problem is chronic or acute in nature. Factors that influence blood pressure include age, stress, ethnicity, gender, medications, activity level, weight and smoking.

Additional steps to be taken with abnormal readings steps include finding out the patient’s usual blood pressure and considering whether the blood pressure was taken incorrectly. Other possible causes for high or low blood pressure are listed in the table below.

Possible causes for abnormal blood pressure
Low blood pressure High blood pressure
Medications: opiates, diuretics, cardiac, hypertensive Medications: vasoconstrictors, IV fluids
Pain, dehydration, blood loss, other volume depletion Fluid overload, pain, anxiety
Anaphylaxis, neurogenic or septic shock, trauma, MI, aortic aneurysm Hypertension, renal failure, stroke, TIA, MI, toxemic pregnancy, aortic aneurysm

(Rathbun & Ruth-Sahd 2009)

The patient’s blood pressure in the case example were elevated (166/94) but we don’t know if he has hypertension that has been untreated or poorly controlled. This blood pressure in the context of rapid pulse, hypothermia and his subjective complaint of a headache three hours after an assault make traumatic injury a strong possibility. A CT scan done at the hospital showed a subdural hematoma.


Because the body has so many mechanisms to maintain homeostasis a full set of vital signs and serial readings will provide more information about the patient’s condition than a single vital sign or a single set of readings. When vital signs are considered a task, rather than a tool, simply collecting the information is sufficient. Nurses who use vital signs as a tool, integrate the information with other information they have about the patient, interpret their meaning and develop a plan that takes into account the likely scenarios that may take place. An essential step in nursing process is the evaluation and reassessment of a patient’s condition so that the plan of care can be adjusted to prevent harm and promote healing (ANA 2013).

  1. What criteria do you use to clear an inmate after an assault?
  2. What should the plan of care for the inmate in this case example have included and why?
  3. What are the ways nurses can evaluate their plan to return an inmate to general population?
  4. How often do you have a full set of vital signs when making this decision and are you able to compare it to a baseline for the particular patient?
  5. How often are you able to consider the full range of possible reasons for abnormal vital signs (reflective thinking) and how often do you rely on pattern recognition?

Vital Signs: Best Practices

Spotlight on Best Practices Words Great Concepts Successful IdeaThe summer before entering college I got a job as an assistant at a retirement home. One evening I was taking an elderly gentleman’s pulse, while together we watched Neil Armstrong’s first walk on the moon. It was in that moment; feeling his strong, steady heartbeat, while sharing the wonder of our Nation’s achievement with him that I decided to become a nurse. I have taken a lot of vital signs since then and they still help me make a connection with the patient.

These tools have been around for more than 100 years. Pulse and respirations were the original vital signs because they only required a timepiece to measure. Although the thermometer was invented by Galileo, its clinical use did not began until the late 1800’s, followed shortly thereafter by blood pressure measurement. With the introduction of the pulse oximeter in the 1980s oxygen saturation has been suggested as a fifth vital sign (Olsen 2012, Tierney, Whooley, and Saint 1997). There is much debate in the literature about the use of vital sign changes to predict decline in physiological status, when and how often vital signs should be taken, and the role of new technologies in monitoring patients. Problems with accuracy of vital signs are attributed to the failure of healthcare professionals to follow recommended practices for measurement (Lockwood, Conroy-Hiller and Page 2004).

The reasons we take our patient’s vital signs include:

  1. Establishing a baseline for each particular patient. These baseline measurements are important because they help us identify changes in the patient’s circulatory, respiratory, neural and endocrine systems.
  2. To diagnose and treat illness. Abnormal vital signs are often the initial indicator of illness or disease and along with subjective and objective data will suggest the next steps that should be taken clinically. We also use vital signs to monitor progress in managing diseases such as hypertension.
  3. To identify risk for and prevent physiological deterioration. Patients often have changes in vital signs six to eight hours before cardiopulmonary arrest or other major organ failure (Storm-Versloot et al 2014, Moldenhauer et al. 2009, Kyriacos, Jelsma and Jordan 2011). Monitoring of patients who are already medically compromised helps us to detect deterioration in physiological status so that measures to prevent an adverse event can be taken.

Summary of recommended best practices for taking vital signs:

Temperature: There are three dimensions to temperature- the core body temperature which is estimated by mechanical means using a thermometer. Another is the patient’s subject feeling of being hot or cold. Last the body’s surface temperature or how hot or cold the patient is to touch (Elliot & Coventry 2012). Touch is remarkably accurate in identifying the presence of fever (Lockwood et al. 2004). The patient’s subjective description “ I feel like I have a fever”, our objective sense of the patient’s surface temperature “feels warm to touch” as well as the mechanical measurement of temperature are all components of the assessment of a patient’s temperature (Elliot & Coventry 2012). Environmental temperature as well as localized heating or cooling of the patient impact the measurement of temperature and should be considered in the evaluation of results (Lockwood et al. 2004, The Joanna Briggs Institute 2005). There is considerable variation in results among the various devices and locations used to measure temperature (oral electric, oral disposable, tympanic etc.) therefore a recommended best practice is to record the type of device used and location temperature was taken when documenting temperature results. For serial monitoring of an ill patient the same device should be noted and used for all measurements (The Joanna Briggs Institute 2005).

Pulse: In addition to rate, important dimensions include strength, regularity or quality, and peripheral equality all of which can only be to be assessed by touch (Elliot & Coventry 2012, Goldberg 2009). I once witnessed a correctional nurse ask an inmate to take his own pulse and tell her what it was rather than touch him herself (?). Eighty six percent of nurses underestimate pulse rate. As the rate increases, the magnitude of error increases. (Lockwood et al. 2004). Best practices are to take the pulse for a full 60 seconds. This way it is more likely that irregularity will be identified and math errors in multiplying a 15 or 30 second count are eliminated (Elliot & Coventry 2012, The Joanna Briggs Institute 2005). A full minute count is especially recommended if the pulse rate is particularly slow or fast. Abnormal rates can be further assessed using a stethoscope to listen to the apical pulse for a full minute (Goldberg 2009, Lockwood et al. 2004).

Respirations: In addition to the rate, observation of respiration includes noting the pattern or rhythm, effort including use of accessory muscles, depth and equality of chest expansion (Elliot & Coventry 2012, The Joanna Briggs Institute 2005). Observing respirations for two 30 second periods or for one 60 second interval provides a more accurate measure of respiratory rate than shorter intervals. Respiratory rate is considered a sensitive indicator of critical illness or an impending adverse event and so should be included in the serial evaluation of any patients presenting in distress (Elliot & Coventry 2012, The Joanna Briggs Institute 2005, Goldberg 2009, Lockwood et al. 2004).

Tissue oxygenation: While this is an important tool in managing patients with cardio-pulmonary disease there is no evidence that routine measurement of pulse oxygen saturation (SpO2 ) makes any difference in managing patients or their clinical outcomes in the ambulatory care setting (Lockwood et al. 2004). Therefore the patient’s SpO2 should be considered part of the evaluation of respirations rather than a separate vital sign (Fetzer 2013). Factors that affect the accuracy in determining SpO2 include any condition that decreases peripheral blood flow (atherosclerosis, vasoconstrictors, peripheral edema, hypothermia etc.) as well as conditions that interfere with transmission of light (nail polish, artificial nails, dark pigmented skin, moisture, jaundice, motion, outside light). Studies show that nurses often lack knowledge of the factors that affect its accuracy (Elliot & Coventry 2012).

Blood pressure: This vital sign is one of the most inaccurately measured by health care professionals and yet is one of the most important in diagnosing, treating and managing disease (Elliot & Coventry 2012, Lockwood et al. 2004). One study reported by the American Heart Association (AHA) found that only two percent of nurses and three percent of physicians measure blood pressure according to the AHA guidelines. Errors were made in placement of the cuff, size of cuff, inflation pressure and placement of the stethoscope (Pickering et al. 2005). Automated blood pressure monitors save time but are considered less accurate than use of proper technique and a sphygmomanometer and stethoscope (Lockwood et al. 2004, Elliot & Coventry 2012, The Joanna Briggs Institute 2005, Pickering et al. 2005). The AHA recommends that clinicians be evaluated and re-coached in technique periodically (Pickering et al. 2005). Best practice recommendations include using the bell rather than diaphragm of the stethoscope, the patient should be sitting with back and legs supported, the patient’s arm should be at heart height and supported at the elbow, the upper arm should be bare or unencumbered by clothing and the width of the cuff should be 40-46% of the circumference of the arm. The cuff should be inflated to 30mmHg above the last systolic pressure or when sound disappears at the brachial artery in the antecubital fossa. Pressure should be deflated at a rate of 2-3 mmHg/second. When blood pressure measures either high or low of normal a second measurement should be taken after consideration of factors that may be affecting the rate (recent exertion, anxiety, position, poor technique, wrong cuff size etc.). Repeated measures are much more valuable in managing hypertension than a single measurement (Fetzer 2013, Lockwood et al. 2004, Elliot & Coventry 2012, The Joanna Briggs Institute 2005, Goldberg 2009, Pickering et al. 2005).

Summary: There is a lot more to taking a patient’s vital signs than simply measuring temperature, pulse, respirations and blood pressure. This review reminds me of how much data can be collected when getting vital signs and how rich it’s meaning becomes when done comprehensively rather than piece meal. I will say that I don’t think I have had my competency taking vital signs evaluated nor has my technique been peer reviewed as recommended by the AHA. Does anyone have a peer review tool or a competency evaluation for vital signs that they would recommend after reviewing the best practices in this post? If so please share by responding in the comments section of this post.For more on the professional practice of nursing in the correctional setting get a copy of our book Essentials of Correctional Nursing.

Vital Signs: Essential Tool or Task?

Stethoscope green colorMr. Phillips is a 48 year old inmate with a history of schizophrenia who was admitted to the facility psych unit a week ago because of refusal to eat and potential for self-harm. On morning rounds, the nurse reports that his blood pressure is low (98/51 mmHg), although all of his other vital signs are within normal limits and he does not have any particular complaints. The primary care provider is contacted and asks that his vital signs be monitored closely. The provider is concerned that Mr. Phillips is dehydrated and asks that drinking water be readily available to him. During the remainder of the day he keeps to his cell and does not take any meals. That evening his vital signs are normal except for blood pressure, which is 88/51 mmHg. The night nurse makes a summary chart note at the end of the shift that Mr. Phillips appeared to sleep without complaint or distress. A few hours later he is found lying in bloody feces and barely responsive to verbal stimuli.

Florence Nightingale said “But if you cannot get the habit of observation one way or other, you had better give up the being a nurse, for it is not your calling, however kind and anxious you may be.” In this case example, the provider asked that Mr. Phillips’ vital signs be monitored closely and yet over the next 20 hours nursing staff only take them once. Taking vital signs is an independent nursing intervention (it does not require a provider order) and is considered an essential tool in the collection of information used by nurses to assess and monitor health status.

Monitoring of health status is described by the Institute of Medicine (IOM) as an important aspect of what nurses do in caring for patients. Monitoring or patient surveillance is defined as purposeful and ongoing collection, interpretation and synthesis of data for clinical decision making with the goal of early identification and prevention of potential problems. The practice includes skill in the use of monitoring devices to measure temperature, pulse, blood pressure, respiration, tissue oxygenation and neurological status. It also includes thinking critically about possible reasons for changes in a patient’s vital signs, to think beyond the obvious in constructing a diagnosis, then formulating a plan and intervening to achieve the identified patient outcomes.

In the correctional setting, the nurse is the initial and primary link a patient has to access care for medical and mental illnesses. Utilization of nursing process, including comprehensive assessment is critical to good patient outcomes in the correctional setting. The first practice standard is that correctional nurses collect comprehensive data in a systematic and ongoing process, using appropriate tools and techniques and then synthesizes the data to construct a coherent whole to plan, provide and direct subsequent care (ANA 2013, White & O’Sullivan 2012).

The function of using vital signs to monitor a patient’s physiological status is among the first subjects taught in nursing school along with the development of skill in using various measurement tools and techniques. However the ability to synthesize the information and come to a clinical judgment requires exposure to many clinical situations and the knowledge garnered from experience. It is only from reflection on clinical experiences that the expertise to form a nursing judgment develops (Rathbun & Ruth-Sahd 2009).

The patient safety and quality improvement literature have emphasized development of early warning systems using numerical parameters set for abnormal vital signs to help identify patients whose physiological status is deteriorating during hospitalization (Whittington et al. 2007). Reasons for establishment of these systems are that nurses fail to detect deterioration in patients because they don’t take vital signs as frequently as they should, nurses wait to take vital signs only when they recognize that the patient is deteriorating and they are overly reliant on their experience to alert them when a patient’s condition is deteriorating (Bunkenborg et al. 2012).

All three of these reasons played into the failure to recognize earlier deterioration of the patient in the case example at the start of this post. The next three posts will address best practices for taking vital signs, the interpretation and synthesis of data collected from vital signs and the concept of clinical triggers in patient care. In the meantime take a moment to conduct your own audit and reflect on the use of vital signs in your setting. Here are some questions to get you started:

  1. Are vital signs treated as a tool or a task?
  2. When do you take vital signs and why?
  3. When do you delegate taking vital signs?
  4. What is the significance of the information collected and how is patient care impacted?

Correctional Nurse Goals for 2015: Expand Your Knowledge

2015 goals on digital tabletHealth care is advancing at the speed of light. We are expected to apply current evidence to our practice and understand the new technologies, medications, and treatments that are being implemented. It can be difficult to merely keep from sliding backward as the treadmill pace ever increases under our feet. That is why my final suggestion for correctional nurse goals for this year is to expand your knowledge about your practice and keep up with the latest developments. Here are a few ideas to get you thinking about ways to improve your foundational correctional nursing knowledge and keep up with changes in nursing practice. Links are provided for easy purchase or subscription.

A Foundational Book Shelf

Every serious correctional nurse should have access to these texts as they are the basis for our specialty practice.

Specialty Periodicals

Journals and magazines provide updates to changing practice and information on movements in the industry.

Ongoing Information Updates

Digital sources keep us posted on day-to-day changes and news of importance to our practice. Although you could go out and regularly check information websites, but I favor sources that collect up the top items and send them to my inbox for scanning. Here are a few of my favorites.

  • Academy Insider – This free weekly email newsletter from the ACHP aggregates correctional health care news and items of interest for those in our field.
  • Medscape for Nurses – Keep up with research and information in the general nursing field with this weekly synopsis sent to your inbox.
  • ANA SmartBrief – Professional news from the American Nursing Association. Keep current on what is going on in our profession.

I’m sure I didn’t include all the possible places for you to gain knowledge and stay on top of changes in our profession and specialty. Share your favorite sources in the comments section of this post.

Correctional Nurse Goals for 2015: Expand Your Network!

2015 goalsIt is pretty easy to feel isolated in correctional nursing practice. We work in a mostly unacknowledged specialty with a patient population that many think do not deserve good nursing care. We can easily feel as vulnerable and marginalized as our patient population. Combine with that the ‘push back’ we can sometimes get from the culture of incarceration (pressure to be less caring and concerned for the well-being of our patients) and it is easy to see why many in our practice settings feel overwhelmed and underappreciated.

That’s why I recommend a goal to network with others in your specialty this year. Developing a network of like-minded nurses who desire to make a difference in their practice in the criminal justice system can be just the ticket to improve your outlook and revitalize your correctional nursing career. Here are a few ideas for how to increase your network in 2015:

Go Local

Nothing beats a face-to-face chat to regain perspective and feel supported. Are there local opportunities to meet with other correctional nurses? For example, does your state prison system host any activities or events that bring nurses together? How about the state nursing association? Some states have specialty practice forums that may include correctional nursing.  Consider a neighboring county jail.  Suggest forming a journal club or meet-and-greet where correctional nurses can gather and develop relationships.

Go National

Another way to network with correctional nurses is to attend a national correctional conference. Your facility management may be involved in the American Correctional Association or the American Jail Association. Both have conferences that are attended by health care staff. See if there may be funding for your attendance this year. (TIP: Before requesting funding, research the event and suggest ways some of the presentation content may be applied to make improvements in your facility).

Other excellent national conference to attend are any by the National Commission on Correctional Health Care (NCCHC) or the American Correctional Health Services Association (ACHSA). These conferences are solely for correctional health care professionals and are attended by many correctional nurses. Opportunities for networking abound during exhibit hours, sessions, and round table discussions. Additionally, regional conferences are offered by ACHSA chapters in California/Nevada, Oregon, and the  Southeast Region.

When attending a conference, be careful to mingle with people you do not know and sit at tables with others you would like to meet. If you attend with a group, make plans to attend different sessions and compare notes rather than traveling about the conference as a group. This will expand your opportunities to meet new people.

Go Social

Social networking is now available through social media outlets such as Facebook and LinkedIn. Both of these platforms have correctional nursing groups were nurses in our specialty share concerns and get advice or direction on issues. Consider connecting with other like-minded nurses working in the criminal justice system by joining these groups:

Correctional Nursing on Facebook

Correctional Nursing on LinkedIn

I hope you expand your correctional nursing connections this year and develop a personal network of fellow nurses. We need encouragement and support to recharge our careers, enhance professional practice in our specialty, and improving health care for our unique patient population!

Correctional Nurse Goals for 2015: Get Certified!

Hand underlining 2015 Goals with red marker, business conceptWhat, you say? Take an exam in 2015? Do I really want to do that? Are these questions running through your mind at the idea of getting a certification this year? Here are some thoughts on why you should consider becoming certified in your specialty this year.

I Have a Nursing License Already

You might be asking yourself – why do I need certification when I have a nursing license? Licensure is definitely required to provide our level of health care. It is a governmental requirement for practice that protects the public from incompetent practitioners. Specific educational requirements, such as the amount of practical hours of training, are often a part of the State Practice Acts governing entry level into the profession.

Certification, on the other hand, is voluntary, non-governmental, and not required to enter into nursing practice. It recognizes an individual’s advanced knowledge and skill beyond initial licensure. Most certification programs require a minimum number of hours of practice in the specialty along with a written certification exam.

Worth the Effort?

Is there value to all the effort it will take to gain certification? The American Board of Nursing Specialties completed research in this area and found these 5 components of certification value. Which ones resonate with your professional values?

Professional Recognition: Probably first and foremost is professional recognition among employers, peers, and consumers. Certification denotes a proven knowledge base and documented experience in a given specialty. I experienced this myself as a consumer this past year when my husband prepared for a total hip replacement. The orthopaedic surgeon looked young to me…a problem I have a lot these days as I am getting older (!). While in the waiting room for the consultation visit, I was contemplating asking that uncomfortable question about how many surgeries of this type he had completed. However, just in time, my eyes fell on a framed certificate of board certification with the American Academy of Orthopaedic Surgeons. That was comforting…as was our conversation with him shortly afterwards where he explained the procedure and volunteered his frequency of performing it. By the way, my husband is doing very well after the surgery and we are very happy with the results.

Professional Credibility: Credibility is another component of certification value. This was important to me when I became a correctional nurse educator 10 years ago. If I was going to be orienting and educating nurses in the specialty, they needed to know that what I was saying was credible and that I knew what I was talking about. One way to do this is through certification. I started on my journey to the basic CCHP certification the first year I was a correctional nurse. Actually, I brought others along with me by starting certification study groups in any facility with interest. We had over 20 people sit for the certification exam after we all studied together. It was exhilarating and I recommend this as an idea for you. Start a study group in your facility and go through the process together.

Sense of Accomplishment: It is easy to see how you would have a sense of accomplishment through successful completion of a specialty certification exam. It can be hard work and you deserve congratulations at the finish line.

Knowledge Validation: Certification validates basic knowledge for the particular specialty – above and beyond initial general professional knowledge.

Marketability: All these outcomes also mean marketability. Certification means you will stand out in a crowd of resumes vying for a particular position. It not only speaks to your knowledge but to your motivation and perseverance in the specialty. Someone who is only passing through is not going to bother with certification. Someone who is not interested in their career is not going to get certified. Someone who is not willing to diligently pursue excellence is not going to be certified. You get the picture. Certification says you are someone who is motivated to do a good job in our specialty.

I hope I have convinced you to consider certification in correctional nursing in 2015. Here are some earlier posts that can help you create an action plan to prepare for certification:
