Managing Medications During Home Hospice Cancer Care: The Needs of Family Caregivers

CONTEXT

Family caregivers (FCGs) are often at the frontline of symptom management for patients with advanced illness in home hospice. FCGs' cognitive, social, and technical skills in complex medication management have been well studied in the literature; however, few studies have tested existing frameworks in clinical cases in home hospice.

OBJECTIVES

This study sought to assess the applicability of caregiver medication management skills framework by Lau et al. in the context of family caregiving in home hospice to further the understanding of FCGs' essential medication management skills.

METHODS

This was a secondary data analysis of 18 audio recorded home hospice visits transcribed verbatim; deductive content analysis of caregiver-nurse interactions was conducted. The target sample included FCGs of hospice patients who had cancer diagnoses in hospices located in the greater urban area of the Rocky Mountain West. Caregiver medication management skills were identified and categorized into the five domains of caregiver expertise. Exemplars of each domain were identified.

RESULTS

An average of four medications (SD = 3.5) was discussed at each home hospice visit. Medication knowledge skills were observed in most home hospice visits (15 of 18). Teamwork skills were observed in 11 of 18 cases, followed by organizational and personhood skills (10 of 18). Symptom management skills occurred in 12 of 18 cases. An additional two subconstructs of the personhood domain-1) advocacy for the caregiver and 2) skills in discontinuing medications-were proposed.

CONCLUSION

These findings support framework by Lau et al. for caregiver medication management skills and expands on the existing domains proposed. Future interventions to assess FCGs' skills are recommended.

Organization, teamwork, and advocacy: Important skills needed by hospice family caregivers who manage medications

121

Background: In the home hospice setting, family caregivers (CGs) often assume medication administration responsibilities traditionally performed by licensed nurses. Little is known about how to assess and support CG medication management skills. As part of an ongoing study of nurse-caregiver interactions in home hospice, we gathered data on CG medication management needs. Methods: A longitudinal, multicenter study of home hospice nurse visits captured audiorecorded communication between nurses and CGs. Participants included patients with cancer and their self-identified CGs who were recruited upon home hospice enrollment. The current sub-study included participants aged ≥65 and their family CGs from 7 hospice agencies. Two investigators independently coded transcriptions of the first audio recorded nurse home visit using a directive content analytic approach to map conversations to a previously published, interview-derived, framework for hospice medication management by CGs. Results: A total of 18 patients (mean age 76.5 [SD 10.7], 56% female) and their CGs (mean age 59.6 [SD13.4], 78% female) were included. Content analysis revealed that CG skills needed for medication management are not limited to drug knowledge. Complicated organizational skills are needed to track medication acquisition and dosing, record the use of short- and long-acting drugs with similar modes of action, and coordinate medication administration by multiple CGs. Teamwork skills are needed to help coordinate medication prescribing between specialist, primary, and hospice physicians. CGs also need symptom management skills regarding the proper selection of medications, as well as skills to manage side effects, inadvertent errors, and possible medication related-emergencies. CGs play a vital role in patient advocacy, alerting providers to the burden and quality of life issues related to medication use, including whether medications have intended or unintended effects, or are potentially unnecessary or causing harm. Conclusions: CGs must have multiple skills to effectively manage medications in home hospice. A systematic approach and intervention is needed to support CGs’ medication management skills.

Vulnerability-based spatial sampling stratification for the National Children's Study, Worcester County, Massachusetts: capturing health-relevant environmental and sociodemographic variability

BACKGROUND

The National Children's Study is the most ambitious study ever attempted in the United States to assess how environmental factors impact child health and development. It aims to follow 100,000 children from gestation until 21 years of age. Success requires breaking new interdisciplinary ground, starting with how to select the sample of > 1,000 children in each of 105 study sites; no standardized protocol exists for stratification of the target population by factoring in the diverse environments it inhabits. Worcester County, Massachusetts, like other sites, stratifies according to local conditions and local knowledge, subject to probability sampling rules.

OBJECTIVES

We answer the following questions: How do we divide Worcester County into viable strata that represent its health-relevant environmental and sociodemographic heterogeneity, subject to sampling rules? What potential does our approach have to inform stratification at other sites?

RESULTS

We developed a multivariable, vulnerability-based method for spatial sampling consisting of two descriptive indices: a hazards/stressors exposure index (comprising three proxy variables), and an adaptive capacity/sociodemographic character index (five variables). Multivariable, health-relevant stratification at the start of the study may improve detection power for environment-child health associations down the line. Eighteen strata capture countywide heterogeneity in the indices and have optimal relative homogeneity within each. They achieve comparable expected birth counts and conform to local concepts of space.

CONCLUSION

The approach offers moderate to high potential to inform other sites, limited by intersite differences in data availability, geodemographics, and technical capacity. Energetic community engagement from the start promotes local stratification coherence, plus vital researcher-community trust and co-ownership for sustainability.

Developing and measuring progress toward collaborative, integrated, interdisciplinary health care teams

In this article we report the results of a longitudinal study of an intervention to enhance interdisciplinary team functioning in a primary care setting. Components of the team development intervention are outlined. Team members' assessments of progress towards expressing values consistent with an effective team--as measured through the System for the Multiple Level Observation of Groups (SYMLOG)--are presented and discussed. Institutional, organizational, and team related supports and barriers that affect the development of collaborative, integrated teams are identified and discussed; implications for ensuring teams' success are presented.

Health status of a low-income vulnerable population in a community health center

Healthcare safety net providers are under increasing pressure to meet the physical and mental health--as well as the range of social service-needs of traditionally vulnerable and hard-to-reach populations. The extent to which health center patients are less well and in poorer health than is the rest of society, thus requiring greater depth and breadth of service, has not generally been the focus of systematic assessment. This case study uses the 12-Item Short-Form Health Survey (SF-12) and selected years of healthy life questions from the National Health Interview Survey to assess the self-perceived health status of patients at one Section 330 community health center in central Massachusetts. Five hundred thirteen patients completed all questions on the SF-12; 619 completed each of the years of healthy life questions. Respondents' physical and mental component summary scores were significantly lower than national norms for all age groups (P < .001). Respondents were also significantly more likely than the civilian noninstitutionalized population to be unable to perform major activities (P < .0001) and to be in fair or poor health (P < .0001). Analyses give an indication of the magnitude of difference in self-perceived health status between this poor, vulnerable population and the citizenry at large and suggest implications for policy related to safety net healthcare facilities.

100% rapid (partial) rescreening for quality assurance

OBJECTIVE

To compare the efficiency of two methods for routine quality assurance in gynecologic cytology: random rescreening of 10% of negative gynecologic smears and rapid rescreening of all negative gynecologic smears.

STUDY DESIGN

All gynecologic smears considered to be negative or benign and diagnosed between November 1, 1996, and December 31, 1997, were rescreened using the rapid, partial rescreening technique. Results were compared to those of the 10% random rescreening method.

RESULTS

Comparing the 10% review of negatives to the rapid rescreening in two comparable periods of three months, the former required review by the supervisor of 160 cases in order to find a true false negative. With rapid rescreening, the supervisor had to review fewer than eight cases to find a true false negative. Also, rapid rescreening found about four times more true false negatives than random 10% review.

CONCLUSION

Rapid rescreening of all negative gynecologic smears proved more efficient than 10% random rescreening.

Maternal serum screening for fetal Down's syndrome, a retrospective study

A retrospective study of the different biochemical markers used in screening for Down's syndrome was carried out on serum from 18,600 women between their 15th and 18th week of pregnancy. Thirty-two sera were from women with fetal Down's syndrome. The retrospective study of these 32 sera involves: (a) the screening of the maternal serum concentrations of human chorionic gonadotropin (hCG) and of alpha-fetoprotein (AFP); (b) the evaluation of the risk of Down's syndrome when screening maternal serum concentrations of hCG alone, then the combination of the two markers and finally the maternal serum concentrations of unconjugated estriol (uE3). The mean of MOM (multiples of the median) for the pathological sera were calculated for hCG (1.91), for AFP (0.63), for the ratio hCG over AFP (3.02) and for uE3 (0.72). With the use of hCG alone we estimated a 41% detection rate for an amniocentesis rate of 5.3%, whereas when hCG was combined with AFP the detection rate approached 65% for an amniocentesis rate of 5.5% at a risk cut-off of 1:300. The results of the uE3 determination confirm the validity of this marker. The comparison of these results with other retrospective studies shows the incidence of different factors in the detection rate such as the choice of markers, the age group studied, the modes of calculating the risk and the actual cut-off chosen.

Coexistence of hypothyroidism and myocardial infarction

OBJECTIVE

To assess the coexistence of overt hypothyroidism and acute myocardial infarction (MI) in respect of clinical and biological manifestations and outcome.

DESIGN

Retrospective study of patients with coincident untreated or uncontrolled hypothyroidism presenting to Notre-Dame Hospital with acute MI. Each patient's MI was matched with two controls for date of admission (within three years) of MI, age, sex, diabetes mellitus and number of previous MIs.

SETTING

All patients were admitted to Notre-Dame Hospital, which is a secondary and tertiary care institution.

PATIENTS

From 1975 to 1990, 5691 patients were seen at the authors' institution with acute MI, of whom 17 had simultaneously an untreated or uncontrolled hypothyroidism. Hypothyroidism was defined as thyroid-stimulating hormone levels greater than 40 mU/L associated with low or normal levels of serum thyroxine.

RESULTS

Chest pain was documented in each case. Electrocardiogram location of the MI was inferior in 10 (59%) patients and in 14 (41%) controls, anterior in seven (41%) patients and in 20 (59%) controls. There was a trend towards higher creatine kinase peak levels in patients with hypothyroidism (1409 +/- 1145 U/L versus 943 +/- 788 U/L). The Killip index was similar in the two groups (1.8 +/- 1 versus 1.8 +/- 1), as was the incidence of arrhythmias (seven of 17 versus 11 of 32). There was no significant difference in mortality between the two groups (18% [three of 17] versus 12% [four of 34]). However, the incidence of residual ischemia was greater in patients with hypothyroidism (12 of 17 versus 10 of 34, P < 0.008).

CONCLUSIONS

Hypothyroidism is not associated with an unfavourable effect on the clinical course of acute MI. However, patients with hypothyroidism seem to have an increased incidence of residual ischemia.

[Plasma beta chorionic gonadotropin between 14 and 20 weeks of amenorrhea: a sign of pregnancy-related hypertension]

A defect of placenta maturation has been described in hypertension of pregnancy. Plasma beta chorionic gonadotropins (beta HCG) of placental origin rise at the onset of pregnancy and reach a peak between 9 and 10 weeks of amenorrhoea. As we were making systematic assays between 14 and 20 weeks in a trisomy detection programme, we looked for differences in plasma beta HCG levels between women with pregnancy-induced arterial hypertension and pregnant women with normal blood pressure. We also studied the predictive value of such assays. Pregnancy-induced hypertension was found in 6 women in a population of 89 nulliparas and in 12 women in a population of 163 multiparas. beta HCG levels were significantly higher in women who later developed hypertension among both nulliparas (52,833 +/- 19,538 IU vs 24,499 +/- 16,485 IU) and multiparas (50,558 +/- 23,597 IU vs 20,911 +/- 11,677 IU). In nulliparas, taking 43,000 IU as threshold of pathology we found that the predictive value of beta HCG was higher than that of other tests which had gone through controlled studies (sensitivity 67 percent, specificity 91.6 percent, positive predictive value 36 percent, negative predictive value 97.4 percent, relative risk 5.4). In multiparas, taking 38,000 as threshold and combining this marker with obstetrical history it was possible to predict the occurrence of hypertension more precisely than with other markers which had gone through controlled studies (sensitivity 66.7 percent, specificity 98 percent, positive predictive value 61.4 percent, negative predictive value 97.3 percent, relative risk 8.4).

Use of solid phase biochemistry for potentiometric enzyme immunoassay of oestradiol-17 beta - preliminary report

The present report gives preliminary results of a new sensitive method for potentiometric determination of oestradiol-17 beta in solution, as an application of the competitive enzyme-linked immunoassay technique. Anti-oestradiol-17 beta antibodies are immobilized on a pig skin gelatin membrane, which is incubated with peroxidase-labelled steroid and oestradiol. After fixation of the membrane onto the sensor of an iodide sensitive electrode, the enzymatic activity was evaluated in the presence of hydrogen peroxide and iodides, the electrode potential being a function of hapten concentration in the solution. The purpose of this preliminary work was to determine the optimized conditions for specificity and sensitivity of the antibody-coated membrane in the presence of peroxidase-labelled oestradiol and oestradiol, and to eliminate possible interferences due to adsorption or ionic fixation of enzyme-labelled steroid. The first tests carried out with oestradiol standard solutions gave satisfactory results at levels ranging from 57 pmol/l to 9.2 nmol/l, suggesting that this new procedure should find application in the determination of oestradiol-17 beta in biological fluids.
