- ItemDesign, feasibility, and acceptability of an intervention using personal digital assistant-based self-monitoring in managing type 2 diabetes.(2008-04-21) Sevick, Mary Ann; Zickmund, Susan; Korytkowski, Mary; Piraino, Beth; Sereika, Susan; Mihalko, Shannon; Snetselaar, Linda; Stumbo, Phyllis; Hausmann, Leslie; Ren, Dianxu; Marsh, Rita; Sakraida, Teresa; Gibson, Jolynn; Safaien, Mehry; Starrett, Terry J; Burke, Lora EBACKGROUND The information processing demands associated with behavioral self management of diabetes are extensive Pairing personal digital assistant PDA based self monitoring with a behavioral self management intervention may improve adherence and patient outcomes METHODS ENHANCE is a randomized controlled trial to test an intervention designed to improve regimen adherence in adults with type 2 diabetes The intervention based on Social Cognitive Theory SCT is paired with PDA based self monitoring In this paper we describe the a manner in which PDA based self monitoring is integrated within the SCT based intervention b feasibility and acceptability of PDA based dietary self monitoring and c issues encountered in teaching participants to self monitor using a PDA RESULTS During the first 30 months of this 5 year study 232 participants were screened and 151 were randomized To date 6 cohorts have completed the study The retention rate is 85 n 129 Of those randomized to the intervention n 74 and completing the study n 61 88 reported understanding the usefulness of PDA monitoring 85 reported ease in entering foods into the device 70 reported ease in interpreting feedback graphs and 82 indicated that they would continue to use the PDA for self monitoring after the study concluded Assuming 3 meals per day participants entered an average of 58 of their meals in their PDA and 43 were entered assuming 4 meals per day If we eliminate from the analysis those individuals who entered less than 10 of their expected meals n 12 the average rate of self monitoring was 69 assuming 3 meals per day and 52 assuming 4 meals per day CONCLUSIONS PDA based dietary monitoring is perceived by participants to be useful and acceptable The approach used to instruct participants in use of the PDA and lessons learned are discussed PDA technology shows promise as a tool for assisting those with type 2 diabetes in their efforts to manage their disease
- ItemA preliminary study of PDA-based dietary self-monitoring in hemodialysis patients.(2005-07-11) Sevick, Mary Ann; Piraino, Beth; Sereika, Susan; Starrett, Terry; Bender, Catherine; Bernardini, Judith; Stark, Susan; Burke, Lora EOBJECTIVE The purpose of this study was to pilot test an intervention to enhance the adherence of study participants to the hemodialysis dietary regimen DESIGN A single case study design was used to examine the potential effectiveness of the intervention over a 4 month period of time SETTING A dialysis center in southwestern Pennsylvania PATIENTS Of the five individuals entered into the study one was male and four were female four were black and one was white Participants were 63 to 70 years of age and had been receiving dialysis for a median of 36 months range 18 to 84 months INTERVENTION The intervention included counseling to enhance self efficacy by a renal dietitian paired with personal digital assistant based dietary self monitoring Participants met twice per week with interventionists during the first 6 weeks weekly during the second 6 week period and biweekly in the final 4 week period MAIN OUTCOME MEASURES Monthly laboratory data regarding serum albumin potassium and phosphorus levels Kt V and data on average monthly interdialytic weight gain were abstracted from the participants medical records C reactive protein level was determined at baseline and at 4 months RESULTS Four of five study participants had an increase in serum albumin level from baseline to their final measurement and one participant maintained a stable albumin level Four of five participants also experienced a small increase in serum phosphorus level Mixed results were obtained with regard to serum potassium and average monthly interdialytic weight gain CONCLUSIONS Because of the small sample and single case study design caution must be used in drawing firm conclusions from this study Data suggest that the intervention may result in improved dietary intake and improved serum albumin levels With increased dietary intake serum phosphorus levels may increase Additional research is needed to determine the potential efficacy and cost effectiveness of this intervention for improving dietary adherence
- ItemSelf-monitoring dietary intake: current and future practices.(2005-07-11) Burke, Lora E; Warziski, Melanie; Starrett, Terry; Choo, Jina; Music, Edvin; Sereika, Susan; Stark, Susan; Sevick, Mary AnnThis article reviews the literature on the use of paper diaries for self monitoring food intake identifies the strengths and limitations of paper and pencil diaries and their new counterpart the electronic diary or personal digital assistant PDA and reports how participants were trained to use a PDA with dietary software in two pilot studies one with hemodialysis patients and the other with participants in a weight loss study The report of the pilot studies focuses on the practical issues encountered in training participants in the use of a PDA and addresses the pros and cons of different dietary software programs Six hemodialysis patients were trained in the first study and seven participants attempting to lose or maintain their weight were trained in the second pilot study The training focused on how to use a PDA and how to navigate the dietary software to self monitor food intake The goals of using the PDA were to improve adherence to the therapeutic diets and to self monitoring Lessons learned from the pilot studies are shared
